Two embodiments of my invention are illustrated in the accompanying drawings, wherein: l f

thereof; Y

Fig. 8 is a part-sectionalI front elevation of the second or preferred form;v

Fig. 4t isa of Fig. 3; l

Fig. 5 is a diagrannnutic horizontal section on line 5 5, Fig. 3;'

Fig. 6 is aplan view lof Fig. 3.

Referring more particularly to the drawings, my invention comprises, in both forms, twol lower metal tanks I and kK soldered at their rims to a plate a; an upper metal tank 0 soldered to a plate VI; vand containing a vertical partition wall d; and a system of connecting pipes. 1

rIhe pipe system, as shown, comprises two horizontal pipes L and, 1W` (represented in dotted lines in Fig. 5) which vconnect the tanks I `and K and, hence, are disposed beneath plate (t, vand are provided with valves L and M', and two| other horizontal pipes N and O which are disposed above said plate and are Aprovided with valves N and O', and which connect, respectively, two pairs of vertical pipes R and S and I and Q, hereinafter termed the main vertical pipes. vThese four pipes P, Q, R and S are indicated in section in Fig. 5 and inpdotted lines in Fig. G; in Figs. l and .3, thepipes P and Q areconcealed behind pipes and R, and

part-sectional side elevationl lends thereofthe pipe'R being v1n Figs. 2'V and L tpipes P and S are concealed behind pipes Q and R; Two sets of secondary vertical pipes I and Kl are also comprised in the system and are furnished with tinned metal `tins or ribs; the pipesjI connecting the lower tank I to the upper tank c, and the pipes K and the other lowery tank K.

The tank I may Vbe used as a boiler and may, therefore, be heated in any suitable wa kfor instance b means of a O'as burner IIl which is arranged in Van open-bot tomed chamber (Figs. V1 4) formed by a depending wall H2 provided at the bottom of said tank. The burner may, ofcourse, be .supplied with gas in any desired manner and it may,`if preferred, be replaced by some other type of heater.y

` `When it is desired to` use the structure above Vdescribedfor hot-water heating, the

cap .t of the upper tank c is remo'vedand water is fed into tank I by means ofva funnel, the Vstem ofwhich'projects into the i I upper end of Fig. 2 is a part-sectional side elevation' pipe R, the latter terminating flush with plate I). The water intank I flows into tank K lthrough the` pipes L and M, filling both pipes and driving out the air; it then rises in all' the vertical pipes until it` reachesand flows over the upper filledtirst.

The air driven out by the rising water is Y discharged through a small vent tube uV (Figs. 1,13 and 6) and through the open-V ing for the cap t. i

The apparatus is thus completely filled and no mo-re air left therein, which is an important feature of the invention because in the absence of air the boiling point of the water is lowered; ed; the valves L', M, N, Of of the four pipes L, M, N, O being closed at first for some minutes and, in consequence, cutting out communication `between tanks, I and K andbetween pipes P'- and Q and pipesS and R, so that the water heated in tank I cannot pass into tank K nor into the pipes P and S connected thereto. tank I becomes lighter when `heated and risesy inthe pipes I', Q and R connected to this tank and flows out into the upper tank c. The four valves L, M', NGO are then opened, and warm water from tank oy forces out the cooler water in the pipes K', P and Sand the tank K, thus producingla discharge into thetank I, through the pipes L, M, N, of the Watercontained in the connecting tank c The water in y pipesand the tank l, due to the varied densities of the water in the pipes and in both tanks. f

The water in tank I becomes hotter and hotter, and flows into the tank c, driving tercontained therein, which is Vheavier and fiows down to tanky K throughl the pipes K, I and S, and through the fourV connectingpipes L, M, N, O to-tankIt'o be heated. ,The Vwaterthus circulates lin a ofthe rooms byineans of thegr-eat heatingv surface ofV the numerous ribs or'iins.- e e vrVhen the above apparatusis to be used for heating with steam` at low pressure, the lowei tanks I randK are three-quarters filled with water, the tank K being' here used lfis-an auxiliary tank. The tank I is then heated underneath; and tlie'steani generated by theheat, being*lighter thanthe air contained inthe system, rises-through the sev` eral pipes I",'Q,R to the upper tank c which it fills and whereit gradually becomes cool.` The cooled-steam becomes heavier and is driven" out of tank o by-in-tlowing hotter steam,l and 'flows down through the pipes Kf, P, Sto tank K.- The opening` lo't the pipes N, O produces an exhaustion' of air and steam from tank Ii, through said pipesinto tan-k I, where theginixture is heated 'aiid, when-lighter, rises through pipes I, Q,- It to tank '0 and ,follows they saine circuit.

As previously stated, the .apparatus may1 alsobe'used as a. cooling device for yfood preservation, as a' retrigerating device for drinks and asa device t'ormaintaining a fresh temperature duringhot summer days. For this purpose, a. hermetic closure V with which the. top of the upper Atankv c is provided, isreino'ved; and through the aper! ture lthus expose l, the said -tank is :'il-led with the usual freezingniixtureotsalt and crushedvice; or i'ithrany other liquid, solid or gaseous chemicals for producing'a low -temperature, either Adirectly in `the case oi solid product-s, orby expansion in the vcase ot' liquil and gaseous" substances, the air inthe roomthus being" cooled `by contact with the tanks, the piping and the iin`s`. Removablel caps "W, X, Y'and Z (Figs` l and 3)ma'y beI provided .onf the tanks to discharge the sediment and Jfor cleaning purposes;

Figs. 3

to 6 show a preferred forni of Y the .invention which, as will be understoodI from a comparison :thereof with Figs. 1 and .2, merely involves .the addition of Vcerf tain parts or features to the structure illustrated-in thev latter igures the two construe# tions being' otherwise Y identical. TheseV added parts comprise a 'suitable number of auxiliary vertical pipes I-I (four, six, eight orV more) which Jconnect' the'V bottom" kof `the tank K to the Vtank c, au expansion chambeil A,Aa'nd an outlet pipe J for discharging the products ot combustion from the 'burner fIIorffothe'r theater chamber or cas- ,mg H.- out and taking the place of the cooler 'w'a' Aerators?, are formed .at their lower ends with' horizontal pairtsMI-I3 (Fig. 3) which extend partway Vacross .the bottom of the tank Iv and` bridge 'the space between the l.latter and the tank K,landtheir upper ends closed path, giving :up its heat to the lair are formed .withhorizo'ntal parts Ht (Figs.

3 andg) which extend tat their free ends beiieathth'e partition d. The expansion chamber A is mounted on top of the tank c,

where it restsionfa fixed insulating plate-gA (Figi.v 3), and `is cnnectedfatitsfbottoin to the lower t'ank'fK by vertical pipe B located externallyfiot' the previously-described piping. The outlet-piped, as inentioned abovefleads the burned i. gases and' products of combustion 4from the'burner chamber Hzfwhere it has a laterally-bent inlet end J" (Fig.I 3) vupwardly through the apparatus;` its upper end being' ,provided with an elbow J 21 (Fig. 4l) which is located immediatelyunder th'evupper plate `b and which I passes outwardly ,i andi ,their down wardly.

In operation, the tankI 'isi heated frein mounted on tankK. The quantity/ot hot water' fiowingi 'up into the tank c is .replaced by an equal quantity of cold water flowing from taiik'K'gthis coldwater, being heated by passing tlirough'the heating Zone, and vliowing` up into tank c, landuso on. Meanwhile,"the water in tankeIfis' heated, and begins Vitscirculating movement as vabove oxplainedj 'e A y The expansion chamberA," whicli'is 'halffilled with water, serves as an auxiliary tank land thus insures the. complete filling ofthe system` with.y water. 'L'Ihisl chamber also 'actsas a regulator, andis used to balance the steamr pressures l'produced `in the apparatus. An `abnorn'ial 'pressure yin the tank a will raise the water level in tank A by means of lthe pipey B, while the air enclosed inthe upper portion of tank A will Ib f`compre`s'sed vuntil balancing, of the pressures liii tanks land Cta'kes place. Then the pressureceases, the waterin tank A returns toits normal v,level.
